Answer:
radius = 156 pm
Explanation:
The relation between radius and edge length of unit cell of BCC is
r=a/4
Given
a = 360 pm
Therefore
r = r = radius = 360/4= 155.88 pm
Or
156 pm
The dissociation of calcium carbonate, CaCO3, to simpler compounds can be expressed as,
CaCO3 --> CaO + CO2
The precipitate is CaO and its amount is calculated through the difference which will give us the answer of 5.6 g.
Answer:
The electronic configuration of the magnesium atom shows that it has two unpaired outermost shell electrons while that of oxygen shows that it has six outermost shell electrons with two of them unpaired.
By means of elecron transfer, magnesium atom donates its two electrons to the oxygen atom to now have a charge of +2 while the oxygen then has a charge of -2. This results in an ionic bonding between the two atoms.

Answer: Subduction zone
Explanation: How do we know the subduction zone exists here? Mostly because of geological data left behind by subduction zone earthquakes, known as megathrust earthquakes. Subduction zones are the only type of plate meeting that can cause earthquakes greater than magnitude 8.5, according to the Pacific Northwest Seismic Network.
